# Constraint components

> Add Constraint components to position, move, and manage GameObjects relative to each other.

Constraint components allow you to control the position, rotation, and scale of GameObjects based on other objects in your scene. They provide a way to create relationships between objects without using parent-child hierarchies or writing custom scripts.

Constraints are useful for character rigging, camera control, and creating relationships between objects. You can use multiple constraints on a single GameObject and blend between multiple source objects to achieve complex behaviors.
